Constructor of inherited class should call super

• MISSING_SUPER_CALL
• Error
• High
• es6

This rule applies when constructor of inherited class does not have super call.

When instantiating the class of such a case, a ReferenceError exception is thrown.

Note: This case could not be a problem if a certain transpiler is used, but it can be good to fix the problem for using native class without the transpiler.

Noncompliant Code Example

class A {}
class B extends A {
    constructor() { // MISSING_SUPER_CALL alarm
        this.prop = 42;
    }
}
var obj = new B();

Compliant Code Example

class A {}
class B extends A {
    constructor() {
        super();
        this.prop = 42;
    }
}
var obj = new B();
